When all of the patient’s natural teeth are missing from the lower or upper jaw (complete edentulous), the ball and socket removable overdenture treatment is usually recommended. Although ball and socket overdentures can be used for both the upper and lower jaw, it is more suited for the lower jaw. This treatment might require 2 to 4 implants, depending on the quality and amount of bone present. The implants used have ball-type inserts that are cemented or screwed into them. The inserts are then fitted into an o-shaped recipient site underneath the dentures.

The fixed bridge dental implant treatment are usually built on implants only or combined with natural teeth and implants by providing support needed by the replacement teeth. The crowns are usually built upon the natural teeth and the implants if this is the recommended treatment plan. The crowns are attached to the implants using a screw or implants. Crowns placed on natural teeth are cemented on. The number of implants needed depends on the number of teeth that have to be replaced.

Dental implants may be used for single tooth replacements to replace back teeth or front teeth. Since pleasing bone cosmetics need to be placed at the front of the teeth, the bone quality and quantity at the graft site must be high; otherwise, bone grafting may have to take place. Prior to the use of dental implants, patients would have had to resort to orthodontic therapy to replace missing front teeth. However, the replacement teeth will not look as realistic as the patient would have liked. Replacement crowns from dental implants look more natural and provide patients with beautiful smiles.

The consultation before getting dental implants involve three parts: the oral examination, the x-ray examination, and the case treatment plan. During the oral exam, your dentist will evaluate the health of your gums and remaining teeth. The quality and quantity of the jaw bone where the teeth was previously located will also be examined. The x-ray exam will help determine if there is enough bone, the density of the bone, and if there is enough bone that runs above the nerve of the lower or upper jaw. Finally, the case treatment plan is when your dentist will make a projection regarding what type of treatment can be done with the bone in your jaw, how many implants will be needed, and if there are any special considerations for your case.

The success rate of dental implants is 90%. Failure usually occurs during the second surgery, when the surgeon discovers that the implant is loose and failed to integrate with the jaw bone. The loose implant is removed and another implant can be placed. Implants usually fail due to infection, surgical trauma, titanium allergies, smoking (which decreases blood flow to the healing gums), and lack of healthy bone (if jaw bone is too small for the implant to stay put, bonding will not happen).

Problems may also arise years after getting dental implants. Gums can get infected bacteria, which leads to a disease called perimplantitis. If untreated, this disease can cause bone loss and also loosens the implant. Another problem that can happen is when the denture itself breaks. This usually occurs when your bite is not aligned properly, putting too much force on the implant. The broken denture can be repaired or removed and replaced.

Not everyone is a candidate for dental implants. Individuals who are most suited for this procedure is one who has good health, healthy gums, and enough bone space in the jaw to allow implants to be attached to the jawbone. Your dentist will have to examine your jaw’s bone structure before deciding if you are suitable for dental implants.

Before you get your dental implants placed, you might need to undergo a procedure called bone augmentation or grafting. This is when the bones in your jaw built up to increase the effectivity of the implants. The bone augmentation is usually done before the implants are placed, and the jaw is given time to heal before installing the implants. Healing time takes about four to twelve months, but you can use ordinary dentures during this time.

A scientific study on how rats with estrogen deficiency may help scientists in further improving dental implants osseointegration. It is defined as how a living bone connects to an artificial implant.

The study published in the latest issue of the Journal of Oral Implantology revealed that alendronate (ALD), an aminobisphosphonate improves the osseointegration in the rat.

In the study, implants placed in rats with estrogen deficiency did not osseointegrate. The probability of losing the implants at 2 weeks was 50 percent, and at 4 weeks just 13 percent of the implant surface remained in contact with bone. Administration of ALD helped to improve the bone-implant contact to 85 percent of the initial value. None of the implants were lost when ALD was administered, and the quality of the bone density improved to 50 percent. Overall, osseointegration of implants was enhanced by ALD.

The American Dental Association recommends two types of dental implants. The first is the Endosteal implants, which involves two surgical procedures. During the first surgery, the implants are planted right onto the jawbone. After the gum tissue heals, the second surgery is performed where a post is connected to the original implant. The artificial tooth can now be attached to the post or grouped on a denture or bridge.

The second type of dental implant is the Subperiosteal implants, which is a metal frame fitted on the jawbone, below the gums. The metal frame gets fixed onto the jawbone while the gums heal. Metal posts attached to the frame protrude out of the gums, and artificial teeth get mounted onto the posts.

In connection with a post we made last March, more people are getting on to the panic stage when it comes to their dental implants.

It seems that people are now questioning and even abstaining from dental implants ever since the February report in Ohio where a woman got sick because of lead found in her multi-unit bridge. It turned out that the material came from China.

The American Dental Association (ADA) said that dental restorations nor implants should not have any kind of lead in them.

“In spite of no new information on the possible extent of this problem, media reports on ‘contaminated’ dental materials produced in foreign dental laboratories have become frequent,” the ADA’s president, Mark J. Feldman, stated in letters to the two agencies. “There are disquieting reports of patients declining recommended treatment because of unsubstantiated fears.”

Dental implants are metal frames or posts that are surgically placed beneath your gums. Once they are put into place, your dentist can put replacement teeth on them. Dental implants are fused to the jawbone, providing stable support for artificial teeth. You don’t have to worry about dentures shifting or slipping in your mouth, which is a very important benefit especially when it comes to eating or talking. The secure fit also helps dentures and individual crows feel more natural than traditional dentures or bridges. Another advantage of dental implants is that adjacent teeth don’t need to be ground down to keep your new replacement tooth in place – unlike ordinary dentures, which need to be attached to the teeth beside the missing tooth.
